Module 7: Full Stack Network Security

What You’ll Learn

In this module, we dive more deeply into networking again since we have had a taste of cyber security. We will learn about access controls, firewalls, proxy servers, honeypots, VPNs, IPSEC, wireless security and IOT security.



Network security is the basis of cyber security operations. In this module we will look at the common security implementations in place and what common weaknesses are. We will learn about this low hanging fruit which are typically overlooked and provide a great way to raise threat awareness.
